• the component has an inlet for filling a first filler.
• the foldable and / or flexible wall of the container can be unfolded and / or stretched.
• the container has a defined spatial shape. Starting from the compact, unfilled component can therefore be provided quickly and with simple means a profile body with concrete dimensions.
• the component also has a filling device for filling a second filler.
• a filling device for filling a second filler.
• the wall of the container can be stabilized, for example by means of a hardenable substance.
• the first filler is different from the second filler and therefore has different material properties.
• the component has an outlet for the first filler.
• This embodiment creates the prerequisite that the first filler after filling can also be drained or escapes.
• the container can thus be emptied and refilled. In this way, a complete, scheduled unfolding of the wall can be achieved in a simple manner and errors in the production of a profile body can be avoided.
• the first filler is gaseous.
• gaseous filler the container of the component for the formation of a profile body can be easily inflated. The risk of disruption here is extremely low.
• a gaseous filler can be easily displaced by a second filler. If the first filler is air or another harmless gas or gas mixture, it can simply be drained through the outlet without any residue being disposed of, or soiling must be remedied.
• the second filler is suitably a solid or a liquid material, but solids are preferred.
• the second filler is a curable substance or a (plastic) foam material. These materials are particularly light and inexpensive and also have some very good insulation, insulation and mechanical properties.
• An advantage of the use of solids such as plastics is also that in case of damage to the wall of the container leakage of the filler can be avoided. This is especially true when the filler is in one piece, such as a cured plastic or a foam material, such as a PU foam.
• Another advantage of using (nitrogen) chewable material is that such substances have a very large volume compared to their starting materials. Therefore, compact plastic cartridges can be used to provide this filler.
• the filling device is arranged in the component. In comparison to a likewise conceivable embodiment with a separate filling device, in this case a small number of individual parts is necessary. It is also important that contact of the user with the second filler is avoided. This prevents soiling and is therefore of great advantage in terms of safety and environmental aspects.
• the filling device is arranged on an outer side of the component.
• This has the advantage that the filling device is easily accessible, so that, for example, possibly provided plastic cartridges or other containers for receiving the second filler, for example, can be inserted into or connected to the filling device only immediately before the introduction of the filler. Under certain circumstances, this can simplify the transport and storage of the component and also enables separate distribution of the individual components.
• the filling device preferably has a triggering mechanism by which the introduction of the second filler is controlled. The control can be done manually and / or automatically. Especially practicable is when the triggering mechanism is pressure dependent.
• At least one fill level indicator for the first filler is provided on the component with which the filling process is monitored and thus complete filling or unfolding of the container with the first filler can be ensured.
• at least one level indicator for the second filler is provided. The level indicators ensure easy and safe handling of the component.
• the invention provides the following method steps, namely first filling the container with the first filler and secondly filling the second filler into the container while displacing the first filler ,
• a first filler is first introduced into the container of the component via the inlet, wherein the foldable and / or flexible wall of the container unfolds and / or expands with increasing filling.
• the second filler is introduced, wherein the first filler is displaced by the outlet of the component.
• the container is already completely unfolded by filling with the first filler before the introduction of the second filler, so that the spatial shape of the profile body which later emerges from the component is always reliably achieved.
• interference with the filling of the second filler is avoided with a simple and inexpensive means and instead ensures a scheduled filling.
• This is particularly important since only the scheduled introduction of the second filler ensures that a profile body with a concrete, predefined shape and with a certain mechanical stability can be provided from the component.
• the inventive method when the second filler is designed such that it can not be drained and refilled. This is the case in particular for hardened plastics and foam materials. For this reason, the method according to the invention is particularly advantageous if a profile body filled with a one-piece solid is to be produced from the component.
• the container is already completely filled with the first filler before filling the second filler.
• the profile body is already finished.
• the second filler which is preferably a solid or a thermosetting or curable material
• the already formed Profi I emotions is then finally filled only and fixed in the desired shape. Disruptions during filling of the second filler by incomplete unfolding can be completely avoided in this way.
• an important embodiment of the invention therefore provides that the second filler is cured or cured after the displacement of the first filler.
• This allows the second filler to be introduced, for example, in liquid form into the container.
• the curing of a previously liquid second filler can be done manually, for example by heat or radiation. It is also conceivable, however, that the filler is formed from one or more components which react with one another during introduction into the container to form a solid.
• the invention also relates to the use of a component according to the invention for producing a profile body. Also included are components which have a plurality of chambers, of which at least one or only one part is constructed according to the invention and is formed by the method according to the invention.

• FIG. 4 shows a profile body produced from the component shown in FIG. 3.
• Fig. 1 shows a generally designated 10 inventive component, with a wall 24 which has a foldable and flexible portion 25 and which forms a container 20 for a filler.
• the component 10 comprises an inlet 21 for filling a first filler into the container 20, and a filling device 23 for filling a second filler into the container 20.
• an outlet 22 for the first filler is provided on the component 10.
• the foldable and flexible portion 25 of the wall which is folded in the representation shown in Fig. 1, is preferably made of a plastic. Regardless of the embodiment shown, however, the flexible section and / or the entire wall can also be made of other materials which are impermeable to the intended fillers, or of composite materials.

• the filling device 23, which is presently arranged within the component 10, is formed by a plastic cartridge which is fastened to the underside of the wall 24.
• the filling device 23 may also be designed and / or arranged differently. It is conceivable, for example, that the filling device is arranged on the outside of the component 10, or that a valve or a pump are provided as a filling device, through which the second filler in the container 20th can be introduced.
• the second filler can be integrated in the filling device 23, or be provided separately from this.
• the filling device 23 has a pressure-dependent release mechanism 231, i. the second filler is filled only when a defined pressure is reached by the filling of the first filler.
• the component 10 has a filling level indicator, not shown, for the first filler, which is formed for example by a pressure gauge or a strain-signaling imprint on the outside of the component 10, and via a likewise not shown level indicator for the second filler 13, the may be formed by a plurality of recessed in the wall 24 viewing window.
